My invention relates to improvements in 3 to constitute the respective front and rear cartons and the objectlof my invention is walls 4- and 5. transverse partitions 6 to construct a collapsible eggcarton formed which are adapted to extend from the front of pasteboard or other suitable substance wall t to the rear wall are integrally formed 5 in which the bottom, side walls, lid and with the front wall and are cutin the fol- 55 transverse `partitions are formed from a uni lowing manner as illustrated in Figure 1.y In tary piece of material. Another object of this ligure the full lines show where the park the invention is to so construct my carton titions are cut and the dottedlines where that it can be securedtogether in its assemthey are bent. f l0 bled form by an integrally formed locking 1 The numerals 7 indicate a plurality of pary60 tongue and thus obviate the necessity of using allel transverse cuts of equal length extend, any form of adhesives, wire staples, etc. lng from inside the outerk or upper edge 8 A yfurther object of the invention is to of the front wall l and? projecting intoa so out and yfold `the adjacent edges of my rectangular strip 9r which isadapted .to lie transverse partitions in relation to the front against the `inner face of the rear wall 5 65 j and rear walls of the carton that they will and constitute an inner wall when the carton swing into their adjusted vertical alignment is in its folded or adjusted position as will when such side wallsy are being bent into be hereinafter explained. 10 and 11 are two their adjusted positions. A still further obseries of aligned longitudinal fcuts. formed ject of my construction is to provide means within the fronty wall t and the strip 9 re 70 for securing the free edge of the lid to the spectively. As illustrated in F igure 1 each main portion ofthe carton so that it is locked pair of cuts 10 and 11 extend downwardly against lateral movement through its transfrom the respective ends of one of the cuts verse and longitudinal engagement with the 7 in parallel relation to the edges of the front v transverse partition members. wall l and strip 9 and terminate at the upper 7 5 My invention consists of a carton conends of diagonalfolding lines 12 and 13 which structed and arranged all as hereinafter more extend from the intersecting points of` the particularly,described and illustrated in the adjacent lower cut7 and the edges of the accompanying drawing in which: front wall 8 and strip 9 respectively7 such Fig. l is a plan view of the cut blank from folding" lines` being directed at an angle of 80 which my carton is formed. .l5 degrees to the edges. It will be seen by Fig. 2 is a perspective view of such blank this method of cutting that vtherQpartitions 6 showing the side walls partially folded are independent ofxeach other and only se-r whereby the transverse partitions arev parcured to the wall't and strip 9 by means of S5 tially swung into their adjusted aligned posithe integral portions through which the fold- 85 tions. ing lines 12 and 13 pass. 14 arefolding lines f Fig. 3 is a perspectiveview of the carton extending'in yparallel relation to the cuts 10 showing it adjusted for the reception of eggs, and r11l from the intersecting points of the the lid being` open. j diagonal folding lines 12 and 13 and cuts l0 Fig. d is a longitudinal vertical sectional 7 kto the opposite edge of each partition7 such 9o view through the line 1f-Li Figure 3. folding linesl permitting the partition porf' Fig. 5 is an end view of the cartonythe'lid tions '15 thus formed to bend in relation to being closed,` and, f f f j the partitions when the carton is being folded f Fig. 6 is a; fragmentary view ofthe longiintofits adjusted position. tudinal kpartition which extends'centrally 16 kis a tongueeut within therear wall 5 95 through the carton. l and'adapted to engage the strip 9-when the y Like characters of reference indicate cor.- carton is in the folded position as illustrated responding 'parts in the different views. f in Figure 3, the strip being inserted behind 1 is the bottom of the carton whichis bent such tongue. 17 is the lid of the carton which upwardly along its front and rear edges 2 and is a'continuation of the wall 5, its outer edge 100 being furnished with a portion 18 which is adapted to be bent at right angles thereto and to constitute a carton engaging portion when the lid is closed.

lWhen it is desired to fold a blank as illustrated in Figure 1 into its adjusted position the strip 9 is first bent upwardly as illustrated in Figure 2 and as the partitions 6 are attached to said strip and the front wall i by means of the portions through which the angularly inclined folding lines 12 and 13 pass its upward movement will cause such transverse partitions to swing upwardly ais illustrated, the portions 15 bending along the folding lines lil until they assume a position at right angles to the partitions, the strip 5 of course coming into contact with the faces of the adjacent bent portions 15. The strip 9' and partitions 6 are next swung in an anticloclrwise direction so that the faces of the bent portions 15 adjacent to the wall il come into contact withits face, such wall in turn being swung upwa dly along thel bending line 2 until it assumes a vertical position andthe strip 9 which is also in a vertical position lies along the bending line 3 of the rear wall 5. Such rear wall ois then swung'upwardly in a clockwise direction until it comes in contact with the strip 9, the tongue 16 engaging the strip which is inserted therebeiind as illustrated in Figures.V rlhe top 17 is then bent downwardly along the folding line 19 and the portion 18 bent in relation to the top along the folding line 20. VUpon reference to Figure 3 which shows the carton in its adjusted position it will be observed that the diagonal bending lines 12 and` 13 in conjunction with 'the cuts 'l' and bending lines 14 form vertically extending pairs of right angle triangular members 21 which protrude upwardly beyond the upper edges of the front and rear walls, such pairs of triangular members being of course formed integrally one with the other, their hypotenuse being either the bending lines 12 or 18. 1 s the inner triangular portions are the upper'ends of the portions 15 which are formed *ing lines 12 and-cuts 7, the portion 18 being adapted toy enter such cuts when the lid is closed. In .lieuv` of providing similar cuts inY the two outer partitions I provide V-shaped cuts 23 in the portion 18 into which the up-Y per edges of the outer partitions 6 enter Vso that whilst the cuts 22m the inner partitions prevent an mwardmovement of the portion 18, the cuts 23 in such portion prevent a lateral movement of the lid.

24 is central partition adapted to extend longitudinally of the carton and provided with a plurality of flare-mouthed slots 25 into which are inserted the transverse partitions 6 when such longitudinal partition is positioned in place. The transverse partitions 6 are also provided with downwardly extending centrally disposed slots 26 adapted to receive the upper portion of the longitudinal partition when it is inserted in position.

.lrom the foregoing description it will be apparent that l have devised a simply and easily adjusted collapsible carton for the reception of eggs in which l have obviated the use of adhesives as a fastening means, the carton being securely held in its assembled forml by means of a self-contained locking tongue. Fui-'the more I have constructed a carton in which each transverse partition is securely retained in its adjusted position when swinging movement thereof which might cause eggbrealrage being obviated through 1 Ll 'porting members which will of course not readily permit of bending in a longitudinal direction and also by so dimensioning my ocliing tongue that Yit extends from the edge of one of the portions 15 to the face of the adjacent transverse partition 'I have prevented any possibility of the partitions having a swinging movement about the bending lines 14 at the juncture of such partitions and the portions 15 lying along the inner face of the front wall 4. By removing the locking tongue from out of engagement with the strip 9 the transverse partitions will'be permitted a swinging movement about their respective bending lines 15 which willallow them to lie fiat against the inner face of the front wall dand thus permit the carton to be folded for transit to the egg, packers and thus permit them to save time in adjusting the carton to receive eggs. Y
